Know bridge behavior and effects under construction loads, service and extream loads. Reduce operational and maintenance cost andmeet the National Bridge Inspection Program.

​Following the historic collapse of the Silver Bridge (suspension bridge) on December 15, 1967, which sent 46 people to their deaths, the safety of bridges wine making another pricipales concerns of the nation.​ Congressional hearings on the failure took place and through testimony it was found that neither states, authorities, counties or municipalities who were owners of bridges had programs in place for structural inspections. After these succes, in 1968 Congress passed the Federal Highway Act: US Code Title 23 Section 151 that set forth the requirement to establish National Bridge Inspection Standards (NBIS). Despite this initiative over time related fatal crashes continued to structural deficiencies which caused changes to the NBIS and development of guidelines.

Common causes of deterioration and failure of bridges are:

​The use of smart structural health smonitoring systems in the highway bridges will help you to meet the NBIS requirements, to have best & better understanding of the structure behavior, early detection and location of failures verification of integrity and structural strength, reduction in costs and inspection periods, improved maintenance programs, increase security and reliability.

Below some of the sensors used to monitor the bridges' behavior and performance:
